dccp: Combine the functionality of enqeueing and cloning

Realising the following call pattern,
 * first dccp_entail() is called to enqueue a new skb and
 * then skb_clone() is called to transmit a clone of that skb,

this patch integrates both interrelated steps into dccp_entail().

Note: the return value of skb_clone is not checked. It may be an idea to add a
      warning if this occurs. In both instances, however, a timer is set for
      retransmission, so that cloning is re-tried via dccp_retransmit_skb().
